High-Performance Piezoelectric Nanogenerators Based on Sol-Gel Synthesized BCZT Hybrid Nanocomposites: DE (Scientific Reports on Measurement and Sensor Technology) - Couverture souple
Synopsis
Piezoelectric nanogenerators (PENGs) convert mechanical energy into electricity for self-powered wearable electronics. This thesis develops eco-friendly lead-free BCZT-MWCNT-PDMS nanocomposites for energy harvesting. BCZT was synthesized by the sol-gel method, enabling stoichiometric control and nanoscale particle formation. An optimized 15 wt.% BCZT composite generated a power density of 15.5 µW/cm³. Incorporating MWCNTs promoted conductive network formation, self-polarization, and dipole alignment without electrical poling. Optimized sonication improved filler dispersion, while 0.5 wt.% MWCNTs at the percolation threshold achieved 35.6 µW/cm³. The influence of calcination temperature (600-1000°C) on BCZT structural and piezoelectric properties was investigated. Calcination at 900°C produced crystalline nanoparticles with an average crystallite size of 18.16 nm and particle size of 68.9 nm. XRD and Raman analyses confirmed high crystallinity and a morphotropic phase boundary, enhancing polarization rotation and domain wall mobility. The optimized BCZT-900/PDMS nanogenerator achieved 7.8 V and 29.5 µW/cm³ under cyclic loading with stable performance over 5000 cycles. Adding 0.5 wt.% MWCNTs increased performance to ±10 V and 53.2 µW/cm³. Monte Carlo Metropolis simulations confirmed the effect of calcination temperature on crystallinity and charge mobility. These results demonstrate scalable, performance PENGs fabricated through an environmentally friendly process.
